Why is it important for Christians to believe in Jesus as the light?

Believing in Jesus as the light is vital for Christians because it directly impacts their understanding of salvation and their relationship with God. In John 12:35-36, Jesus urges His listeners to 'walk while you have the light,’ underscoring the urgency of acknowledging His truth before it is too late. This belief leads to spiritual enlightenment, allowing followers to comprehend their own sinful state and the grace that God extends through His Son.

Jesus being the light implies that He discloses the true nature of God and His holiness. When individuals believe in Him, they are accepting the only clarity available about both God's character and their own sinful need for redemption. As proclaimed in John 3:18, 'He that believeth on him is not condemned,' which illustrates the assurance believers have of their acceptance before a holy God. Recognizing Christ as the light also fosters a sense of community among believers, who share the light of Christ with each other, as seen in 1 John 1:7, where walking in the light fosters fellowship and continual cleansing from sin.
